HydraTong ARN-270

In addition, the unit has a modular design allowing interchanging between different modules, e.g. from a ordinary drill pipe module to casing tong modules. Since the ARN optionally can be delivered with powered slew rotation and skid unit, this provides various drill floor lay out alternatives, like rotate and extend between two or more pipe targets or skid to a park position when other tools requires the drill floor area. The combination of the articulated arms and the skid could also give extra high stick up height.*

By utilizing the slew function eventually combined with the skid option, the ARN could act as back up when installed on drill floors with dual roughnecks.

The ARN-270 includes the latest Torque Wrench design, which allows 60° rotation, which ensures efficiency during make and brake of single drill pipes and stands.

Better and more accurate torque is ensured due to optimized triple grip design, providing less box deformation and control of the torque parameters.

The torque wrench is self-centering with a flexible suspension system, eliminating alignment problems.

By considering service life time and maintenance availability, the Torque Wrench design has a robust construction, low part count and minimized need of lubrication by utilizing the latest bearing technology.

Together with available options as pipe doper and mud bucket, it is possible to obtain smooth and effective pipe connection sequences in an automated drilling system.
